Running a language model on your own server instead of the cloud preserves privacy and ends API dependency. But how is it done? The hardware needed, local runtime tools like Ollama, open models (Llama, DeepSeek, Mistral), quantization, RAG on your own documents and securing the local model. A practical, sourced local LLM setup guide for organizations.
Read moreYour employees may be pasting customer data, source code and contracts into cloud based AI tools to speed up their work. This is called Shadow AI and it is one of the biggest unnoticed data leakage channels. We explain what Shadow AI is, how data leaks, the KVKK risk, and how to solve it with a local model and a usage policy rather than a ban, with sources.
Read moreCloud based AI is powerful, but it sends every query, code and piece of data to another company's server. In work that requires security and privacy this is unacceptable. Local (offline) AI runs models on your own hardware, giving the power of AI without the data ever leaving. We explain what local AI is, why it is critical for data sovereignty and KVKK, and why DSET's KAOS engine runs fully local, with sources.
Read moreIf you have lost data in Istanbul, whether a business server, a personal laptop or a phone, the first rule is not to touch the device and not to keep powering it. We explain the whole data recovery process, failure types and how to choose the right service for individuals and companies in Istanbul, with our cargo flow to the Ankara Hacettepe Teknokent lab, cleanroom and PC-3000 hardware, a free diagnosis and a no data no fee approach.
Read moreBefore an attacker attacks your company, they collect every piece of information exposed about you on the internet, open ports, forgotten subdomains, leaked employee emails, exposed panels and social media traces. This is called the external attack surface and OSINT. We explain how the attacker sees you, what information leaks and how to narrow your attack surface, with sources.
Read moreThe password you signed up to a site with ends up in attackers' hands when that site is breached. If you used the same password elsewhere, attackers try it on your other accounts with automated tools, this is called credential stuffing. We explain where leaked passwords come from, how accounts are taken over automatically, and how to protect yourself with unique passwords, 2FA and passkeys, with sources.
Read moreWhen you point a subdomain (like blog.yourcompany.com) to a cloud service and then close that service, the DNS record is left dangling. An attacker can seize your subdomain by claiming that service in their own name. This vulnerability is used for phishing on your domain, cookie theft and brand abuse. We explain how subdomain takeover happens, its effects and how to prevent it, with sources.
Read moreWhen an API key, database password or secret token stays embedded in code or accidentally leaks to GitHub, a frontend bundle or a backup, attackers find it within minutes. The result can be your cloud account being taken over, a data breach and high bills. We explain how leaked keys are found, their effects, and how to prevent them with secrets management, with sources.
Read moreIf your domain has no DMARC record, an attacker can send fake email in your name, from your domain. This vulnerability is used to phish your customers, commit invoice fraud and destroy your brand reputation. We explain how this vulnerability works, its effects, how to test whether your domain is exposed, and how to close it with SPF, DKIM and DMARC, with sources.
Read moreIf you run an e-commerce site, corporate website or web application in Istanbul, your site's security is both your reputation and your KVKK obligation. The most common web attacks, why penetration testing is needed, WAF and basic hardening, KVKK compliance, and choosing the right security service in Istanbul. A sourced, actionable guide.
Read moreiCloud is your phone's most important backup, but just as much a valuable target. The way to protect your Apple ID and iCloud data is a strong password, two factor authentication, a recovery key, and correctly using Advanced Data Protection (ADP), which provides end to end encryption. We explain what is encrypted, what is not protected, and how to secure your account, with sources.
Read moreData recovery is a last resort, the real work is protecting data before you lose it. The way to protect the photos, messages and accounts on your phone is correct backup, full disk encryption, a strong screen lock, theft and remote wipe measures, and managing app permissions. A step by step, sourced protection guide for Android and iPhone.
